Sarah Elizabeth Hollier b.1860

Peter Copsey sent through the lastest Marriage Challenge results from Pancras, which included an 1893 marriage for Sarah Elizabeth Hollier, until now a mystery to me. She married William Chapman, but she states no father on the marriage certificate. From her stated age and the 1901 census entry, I realized she was the Sarah Hollier born 1860 and originally thought to be a late child of Richard and Amelia Hollier at Sydenham. However, I already knew that the 1861 census shows her as a grandaughter, not daughter. A bit more digging shows her in the 1871 census as Sarah Jones, living with her mother Adelaide, by then married to Alfred Jones. I also found Sarah Hollier as a servant at Thame in 1881 and Bloomsbury in 1891. Another puzzle solved.
